Today, ESA’s Gaia mission releases its new treasure trove of data about our home galaxy. Astronomers, led by the Leiden astronomer Anthony Brown, describe strange ‘starquakes’, stellar DNA, asymmetric motions and other fascinating insights in this most detailed Milky Way survey to date.

How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

Regardless of whether you work at a desk or in a lab, all workplaces have their risks. As your employer, the University aims to create a healthy workplace and to limit possible health risks. Here you will find the main risks and measures that we take to reduce them.

Developing a better treatment for patients with head and neck cancer, that is what Binanox, The 2022 iGEM Leiden team, want to achieve. They hope to raise at least 10,000 euros for this cause. Support their crowdfunding campaign today.

Astronomers have found complex organic ice outside the Milky Way for the first time. The discovery shows that the building blocks of life could arise early in the universe - and under a variety of conditions, said Leiden astronomer Will Rocha.

Nerve pain is one of the most common side effects of chemotherapy. It is therefore one of the biggest reasons for cancer patients to stop treatment early. Darcy Reynolds worked on new drug candidates against this pain during her bachelor's thesis. She developed a new series of molecules that increase…

Genes predict whether you have a propensity for an illness but environmental factors often have the last word: nutrition, air pollution, lifestyle, stress. The exposome as both culprit and chance. Large-scale research is being carried out into this at Leiden. Thomas Hankemeier, Professor of Analytical…

Is it a coincidence that three chemists from the same department have each independently received a ZonMw grant? 'No,' the researchers agree in unison. 'The role of chemistry in medical biology is becoming increasingly important, and we’ve worked hard to make this happen.'

A team led by Leiden University in the Netherlands and the National Radio Astronomy Observatory have, for the first time, robustly detected semi-heavy water ice around a young sunlike star. In this ice, some of the ordinary hydrogen atoms have been replaced by deuterium, a heavier variant of hydroge…

An international team of astronomers including Leiden professor Ewine van Dishoeck has observed the benzene molecule (C6H6) in a planet-forming disk around a young star for the first time. The observations tell us more about the forming of planets in this disc, like our own Earth. The scientists publish…

We all know smoking is bad for our health. But we might not have known that the cigarette filters that litter our streets also impact the environment. Esther Kentin is a lecturer at Leiden Law School. She is raising awareness of the University’s cigarette butt problem.

An international team of astronomers, led by Will Rocha of Leiden Observatory, using the NASA/ESA/CSA James Webb Space Telescope have discovered that the key ingredients for making potentially habitable worlds are present in early-stage protostars, where planets have not yet formed.

In the Philippines, Indigenous communities have been harvesting wild honey for centuries. A new chemical analysis of this honey now provides insights into the biodiversity of the region. ‘And an additional reason to protect the national tree properly,’ says lecturer Merlijn van Weerd of the Centre for…

Researchers from Leiden University, University of York, University of Barcelona/IQTCUB/ICREA and The Francis Crick Institute report a new class of experimental compounds that powerfully block influenza viruses. The findings offer a potential new strategy for treating flu infections and preparing for…

In het Leids Universitair Medisch Centrum wordt gewerkt aan de ontwikkeling van een nieuw malariavaccin dat effectiever is dan de huidige vaccins.

Leiden researchers have discovered an enzyme that helps bacteria feed on everyday plastics. This common enzyme could play a crucial role in future research and eventually in addressing the global plastic crisis. The study was published in Nature Communications.

Smart drug carriers, uneven cosmic expansion, and solar energy storage in molecules. These are the topics of three newly awarded NWO-XS grants to researchers at the Faculty of Science.

Gerard van Westen has received the KNCV Gold Medal, the most important Dutch award for chemists under 40. 'It's a huge honour,' says the professor of AI and medicinal chemistry. 'I am now part of the group of people I was always impressed by.'

How do organs work in the body, and how can we create mini-organs to study diseases and test new medicines? That’s the idea behind organ-on-a-chip technology. During his PhD, Flavio Bonanini worked on developing the best possible mini-livers. ‘Make them as simple as possible, and as complex as neede…

On 15 April, our much-beloved and highly respected former colleague Dr Hans Brussee passed away from cancer. In January 2025, Hans began experiencing neck pain. Initially, it appeared to be a herniated disc, but sadly, the diagnosis was soon revised, and his condition proved untreatable. Hans was 77…

To understand how the brain works, it is essential to map it out in detail. This appears to be possible with a microscopy technique in which Leiden physicists excel. This breakthrough could significantly advance the human quest to understand brain functions.

Two research groups involving Leiden University have been awarded a major European grant, the ERC Synergy Grant. This for research on the development of membranes that can clean water and purify medical drugs and research on the biological clock in certain bacteria.

Two consortia led by Leiden researchers have been awarded over one million euros by the Dutch Research Council and the Ministry of Health, Welfare and Sport to find solutions to antimicrobial resistance.

Leiden University, together with Utrecht University, the LUMC and 10 other Dutch universities and institutes, has been awarded a grant of more than €30 million in the NWO call Roadmap Large-scale Scientific Infrastructure (GWI).

Computer scientist Tim Coopmans uses pen, paper and regular computers to simulate the best possible quantum computer. He tells about his research and how this helps make a useful quantum computer a reality a little bit sooner. ‘I hope I will get to see quantum computers contributing something really…

Nanomaterials can pass much further along the food chain than was previously thought. The particles can change shape and size in each organism, enabling them to pass on to the next one in the chain. Researchers from the Institute of Environmental Sciences discovered this accidentally when using a novel…

Researcher Femke Reidsma has been awarded a prestigious Rubicon grant. With this fellowship, she will spend two years conducting research at Harvard University, where she will join a leading paleoecology laboratory.

Leiden researchers, led by Sebastian Pomplun developed a new method to screen hundreds of thousands of molecules for drug discovery, using mass spectrometry instead of DNA tags. ‘We wanted to make drug discovery faster and more accessible.’

On 18 February 2023, our esteemed former colleague Robert Louw passed away. Rob was 86 years old.
